Vegas Movie Studio Platinum (Version 17.0, Build 204) seems to max out on frame size 3840 x 2160 and when I render my 4098 x 3112 video (30 fps) to MP4 (which seems to offer the largest frame size available in this software), the final rendered file video does not fill my monitor screen vertically like the original source video. I'd really like my rendering frame size to match my source video. Is the 3840 x 2160 actually the limit for Vegas Movie Studio Platinum?
